Is there a book or resource where I could evaluate federal and georgian farmhouses in measured drawings? I want to build a farmhouse to blend with those in rural Berks County Pa and cannot find a good reference. Everything is either just pictures without a scale or molding drawings without the house. I want to determine the window fenestration and get the proportion worked out, but I don't have the original documents to work from, I don't have access to any original homes, and I don't know any architects or archive people to track the materials I want. Any help is a plus. thank you.
